Have you tried Quantum Collapse? That was a pretty good one for what it's worth with controls on the iPhone. I thought it worked real well, was a lot of fun, and I still play that sh!t from time to time.
A better version of Fallings Sands. Something like http://www.notdoppler.com/frame/639.html I love that flash game, i wish something like that came on the appstore. I already tried Falling Sands on the appstore from Zodtd but it is kinda old now. The second one sucks.
Again, I say it. A REAL MGS game... I can't get over the lameness of MGSTouch. That, and a real Castlevania game. Other than that, all I really want now is for the rest of the Phoenix Wright series to come as DLC for the original game. I'd pay upwards of $10 per game for that.
I would love to see a online multiplayer pirate mmo. where you can trade, raid cities and stuff. a huge turn off in a pirate game for me is every one gets a ship. ships should be hard to get and earned so when you die and lose the ship it feels like a huge loss. but owning a ship has huge rewards. and to be able to get a ship you have to work on other captains ship or get lucky at the poker table. puzzle pirates is the only thing close to this but I am not a big fan of the puzzles. and i know this will never happen just a dream .
